Power Cards: Your basic attack and defense, Power Cards have a value from 1 to 8. Depending on your character's abilities, he or she (or it, I guess) may use anything at or below his ability level. There were originally three types of Power Cards: Energy, Fighting, and Strength. Later on, Marvel added Intellect.

Character Cards: These are your superheroes and villains. I've basically already described their characateristics in Power Cards.

Basic Universe Cards: These cards represent situations within the game. They have ability requirements and give your heroes bonuses depending on the card. Basic Universe Cards must be discarded after use.

Universe: Training Cards: These cards represent weaknesses in certain characters' abilities. By matching up a maximum ability score, you may give your characters bonuses just like Basic Universe Cards.

Universe: Teamwork Cards: Represent an allied assault by two or more of your superheroes. The combined attack yields superior results.

Universe: Ally Cards: Again, like Basic Universe Cards, these cards provide bonuses to your superheroes by having allies - not necessarily other playable characters - jump in and provide temporary aid during battle.

Tactic: Doubleshot Cards: Like Universe: Teamwork Cards, Tactic: Doubleshot Cards represent two teammates working together in attack or defense.

Tactic: Artifact Cards: Represent the mysterious artifcats that reside in the Marvel universe. These strange and sometimes out-of-this-worldrelics provide great strength to those who can use them.

Special Cards: Yeah, Marvel is running out of names now. Special Cards represent the special, innate abilities of each superhero and villain - each character has their own specials.

Mission Cards: The mission objectives and requirements appear on these cards. They are used to keep track of who is winning the game as well.

Event Cards: As unique to each mission as Special Cards are to each character, Event Cards represent different situations during the missions and always effect both players.

Location Cards: Introduced in Monumental Overpower, Location Cards give bonuses (found on its Innate Ability) to the characters found on its Character List. Location Cards can serve as your Home Base or your Battlesite.

Activator Cards: Other Character Cards that can be shuffled in your deck to assist you if you are using certain Location Cards.
